Suddenly my gas gauge isn't working ('77, L82, 4SPD), sitting on dead empty. Just filled up. I'd appreciate any help I can get.
I have power in and out of the fuse, if I'm checking the right one. The 3rd one up on the right, marked "gauges", with the red stripe? Anyone know?
The troubleshooting guides I've looked at have me dropping the tank next, to access the power, resistor wire, and ground on the sending unit.
Anything 'easier' I can look at before I start that?
Anyone know where the sending unit ground attaches? Can I see that under the car without dropping the tank?
A side question, what is that connector with the pink/black wires, not connected to anything?
Look for the wire harness that comes off the top of the tank. You might be able to get to the sending unit connection thru the fill hole in the body. You might also try to just connect the tank to a good ground.
Is your gauge reading past full or empty? That could tell you if it's open or shorted.
You are looking at the correct fuse. Willcox has a troubleshooting guide on their website.
The pink/black is just a spare connector for an ignition on accessory.
Upload the file above and save it to your desktop. Then look at the picture below and post what your gauge is reading... A fuel gauge in most cases will tell you what the issue is and that will put you on the fast track to fixing it.

And while this say's 1968-1976... the same applies to your car.
